Be it known that l, CHARLFS B. KING, a citizen ofvtheUmted States, residing at Detz'oit, county of Wayne, State of Michigan, ,have invented a certain new and useful Improvement in Transmissionhlechanisni for iaiiiomohiles, ant. declare thefOllOWlllg to be a full, clear, and exact description of the same, such as will enable others skill d in the art to which it pertains to make and. use the same, reference being had so the accompanying drawings, which form a part of this specification.

My invention relates to transmission mechanismfor automobiles, and theobject of my improvements is to provide an ini proved transmission mechanism and one that is compact and easily assembled, l accomplish this object in the apps-rates illustrated the accompanying drawings, in which,.

Figure 1, is a sec'ional plan'view of a mechanism embodyin my invention, and so much of an automo ile as is; necessary to illustrate its connection thcrewith.,1- Fig. 2, is a view oi. the imain shaft of the change speed gear, the sleeve encirolingits and hein section, Fig. .3,,is a sectional elevation tel-zen on the line 33 of Fig. 2, 1001;

ing iii ihe direction of the arrows, but showing the sleeve in full; Fig-Ml, is a per) spec-hive view of ihe endv cities-main shaft the change 'speec gear. Fig. 5, a pen spective view of the end of isho iransmission shaft which engages the end of the nain shale of the change speed gear. -Fig."6,'is

a sectional plan view of the heaiin at the ehcl the transmission shaft Whic is adjacent icowthe rear axle of the vehicle,

' A, the main shaft of the engine anxl A is the fly-wheel thereon;

B, is a bearing for the main shaft A. 4

O, is the main shaft of the change speed gear.

0 represents the clulchhy which-the shaft C may be engaged and disengaged i'rom the main shaft A of the engine.

E, indicates the squared porcion towarcl. the end of the C on which one of the Wheels of the change speed gear (inciieated. in clotte lines) may slide. At the anal and their concerts, as shown most distinctly 1n Fl 4;, a, is the transmission shaft, t is is pro- .videcl With/two zaiunnions a, g, exceeding at right angles thereto and upon these l runnions' are rotatably fiXBCl squ arezl blocks H, H, which blocks fit between the fork-ii? f, f, their surface contacting the inner parallel surfaces of said forks so as to sliclably engage the same The outer ends of the trunnions g, g, and blocks H, H, are foimeil in the arcs of a circle to corz espcnol to the iner surfaces of the sleeve 1 to which. surfaces they are acljacent when the mecha nism is assembled, The construction, jush tlisclosecl forms a universal joint, the'enal of the, shaft G being held in relative ositioii iothat of the shaft E by the iorlzs j, and

.' the surroundingsleeve I;

L, is the change speed gear case. which is fixed to the frame or chassis ofshevehiclei lVlQ-is a cylindrical bearing on 'geac case having its axis coincident with the axis of she shall; (1

N, is a cylindrical portion. of the gear casingfiL coaxial with M,-having amend opening toward the rear axle of the vehicle aiiil having its inner si ifaceadjacent to its open and screw threadeii.

K, is a sleeve fitted upon the sleeve I and -proviileii at its ends toward the i'eai' axle with a portion having an outersurfec'e oonstitching thezone of a sphere, whose center is upon the a-xis of'the-shafi; C.

Q, is a casing surrouncling the transmission shaft. G -and having at its eiiil remote from the rear a xl e 'of the vehicle abortion g having an innei' 'sin'face correspcn ing to' that of the part, K and fitling thereagainsl The outer surfaces of the portion g is also formed iniihe zone of .the su'rfaces of a sphere having its center 'coinoiilene Wit-i that of its ianee'suri 'ace-and with that, of the, outer surfaces the portion 1 0, is an anmili s or spherical retaining cola'r having a cross section adapted to fill .the space between the outer surface oi, ihe portion. g anal the inner cylihcli'ical surface of the cylinclrical portion N of the change J;

speed gear L. The inner eurtaeea ot' the annulus y) tits againet the outer surfaces oi. the portion of the transmission sha'tt casing Q. n

l, in a screw threaded nut engaging the screw threads on the inner surtaee ot the cylinder it and acting to hold the annulus y) in poeition and in close engagement with the portion g of the transmission shaft easing Q.

The end of the sleeve 1 which i;-; toward the engine is provided with screw threads 5 on its outer surface.

J, is a nut engaging the screw threads i and serving to hold the sleeve K in position on the sleeve 1. The cylindrical portion of the sleeve K forms a bushing tor the eyliruler M in which bushing the sleeve I is adapted to rotate.

ll, is the casing for the equalizing gear which forms a portion of the casing for the rear axle B.

til is; a bevel gear Wheel upon the end of the shaft G, and T, is a bevel gear wheel forming part of the driving gear with which the gear Wheel S engages.

U and V are hall races on the end of the transmission shatt G.

ll, is the cup havingan end opening to ward the rear axle and forming the corresponding way of the balls which engage in. the hall race V.

X, is a cup having its end opening away front the rear axle and forming a eorreaponding part of the hall race U.

Y, is a set screw haviin;- a beveled inner end so located in a part of the casing Q, that its beveled end shall engage the sliding portion of the cup X to hold the same in position.

By the construction above. described, I do lfw{tZ"WllZl1 the necessity of another bearing easily assembled and taken apart. nee oi the single serew if, the hall bearing seaired arourately in position.
